The apparatus consists of a hollow metal tube through which first tap water and then steam is passed. The
change in length, A/= 1₂-11, is measured by means of an optical lever, and the temperature at equilibrium
in each case read off the thermometer inserted into the tube.

The apparatus consists of a hollow metal tube through which first tap water and then steam is passed. This process is accurate because it gives a result close to the required value. This is further explained below.

What is an accurate experiment?

Generally, An experiment's accuracy is simply defined as the degree to which the final result is within the bounds of what is considered to be the accurate or approved value. As the distance decreases, so does the precision of the experiment.

In conclusion, Metal tubing, first filled with tap water, and subsequently steam, is used to create the device's steam. This method is accurate since it returns a value that is near to what is needed.
